Girls don't send text messages on their own initiative.

As you know, some people are passive and others are active. How is she? Probably out of politeness, afraid of snubbing you. I am married. For example, I never take the initiative to contact male students, but when they send me a message, I will reply in seconds. I am afraid that I will leave others cold. If you two are not married, you may not be the person she likes. If so, she should take the initiative to find some topics to communicate with you. It's up to you If you like her! Take the initiative! Be bold, she may not hate you, this is a good start! I wish you an early and beautiful return!
